A British diplomat has been hailed as a hero after he dived into a river to save a drowning Chinese woman. Footage filmed by onlookers showed her struggle in the current, disappear under a footbridge and emerge face down, apparently unconscious. Stephen Ellison took off his shoes and dived in to save her. Critics on social media asked why so many Chinese people seemed to be watching her drowning from the side of the river instead of intervening to save her life.
